Hello,
I'm trying to help a friend of mine from Italy. She has a S2 which had the strange problem that phoning was not possible.
First thing I did was resetting the phone which didn't help. Then I flashed paranoid android and at first it worked with Italian Sim Cards.
The phone was left untouched for a few weeks. When I used it, the old problem was back. Then I tried flashing CM, didn't work. Then the Samsung Stock Rom for Italy, then for Germany, then a branded one (the original), downgraded version also. Still, it didn't work. Just the mobile internet worked. IMEI is not corrupted.
The really strange thing is that every time it worked with my German Sim Card - over Roaming. I could call someone and receive calls.
Technically speaking, there is just one modem for both roaming and national calls, right? But how is it possible that it doesn't work for national calls? I tried several providers, but nothing.
When you say 'mobile internet works', do you mean 3g or wi fi?
If you mean wi fi and not 3g....is it possible that the phone has been blacklisted or the sim blocked?
Have you tried searching for and selecting the correct carrier in the phones settings?

No, I mean 3G. I don't think it's possible, she bought it regularly in a shop and had suddenly this problem. But what could be a reason for banning it?
Yes, I tried to connect manually. Different carries are found, but it cannot connect to any carrier, it says try later!
Check the battery.
Try some other battery you will be shocked to know that its caused due to battery loosing current and this especially happens on low charge levels

You need to ask the network if they are having problems .
Have you checked /remade your network settings ??
Could be a rom problem a modem problem a sim card problem or even a CSC problem with wrong settings .
Check settings clean sim card that does not help put your phone back to a warranty state flash stock rom and clear rom counter . Test if faulty take to a service centre .

Im on 3 also i have had a few times the same problem mate, lets say maybe 4 or 5 times, it usually happens if i lose my internet connection it still shows me having signal but cant make a call or sms. i got no answer from 3 either
Check the status screen. I get this and when it happens where it should say T-Mobile it says Emergency Calls Only. I figured my SIM card was at fault so wedged some paper behind it to hold it in place and the problem has almost completely stopped.

Are you guys running an I-9100T from 3? All modems from any rom you install won't work with the T. You'll need your stock KF4 modem.
Get it here:

I had a similar problem. Read more about it here:
http://forum.xda-developers.com/showthread.php?t=1225849
tried going back to kf4 still no luck its only in certain places in me house where it does it everywhere else i have 1 or 2 or none at all bars of signal
3 customer service rang me up told them i wanted cancel the contract bcus of it. they knocked the contract price down from £30 to £25.75 for the text 500 plan with them. bit annoyed that i can only get signal in certain places of me house but cant argue on the price as well as gettin the phone for free
because 3 dont have a 2g network in the UK so if you dont have 3g coverage it will show a network signal but you cant make calls or sms
I'm having the same problem but with o2. I lose signal regularly at home as I live on the perimeter, but when I get signal bars back againwhen i go into town, it tells me that the network is unavailable. I have to switch off and on again to re register and then it works fine again until the next time the signal is dropped... It's annoying in the morning because i can wake up and see full signal on the phone all morning, but people are trying to contact me and not getting through because in reality, the network is not connected! I'm sure o2 have a 2g network, so I would presume it's a phone issue...
Hi all,
I live in France using SFR network and I get the same issue here using KI3 but I had the same problem with KH3.
the behavior on the phone is network seems to be good everytime/everywhere but sometimes people who try to reach me go directly to my voicemail and I receive sms with some delays.
When network works again, I mean I don't see it but I know it because I receive a couple of sms at the same time and a call from my voicemail
it means that my phone seems to be connected to the gsm network but is not, It loose the gsm network...
If you can give me your experience.
thx
I've got the same issue. (tacticman), I'm also on SFR network, i had this since KH3, never before. Now i'm on KI3, it's still here.
I always use CF-Root kernel, i tried to wipe, restore old backups, it does not change anything. I also tried GS II repair tools, nothing too...
The only thing I found to solve (temporarly) the problem, switch to offline mode (mode Hors ligne in FR) and then disable it.
But the problem occurs very often, it's very disturbing.
My IMEI number is still here.
Hi guys I got a big problem, hope u can help.
I have this phone for a couple month already, when I was still running stock I discovered my cell phone would tell me I got no signal. Turning on air plane mode and then turning it off didn't help to get back signal. So I had to turn off the phone and turn it back on to get back my signal. Problem is I never know when it happens until my wife asks me y my cell phone is switched off. So I went ahead rooting it and I flashed a rom on it. But problem isn't gone. I still lose signal but on this rom it shows me full bars, only cannot make phone calls,SMS,and gprs. Tells me no network or no sim card is inserted. I always have to turn off and turn it back on. Now that it is rooted with whatever firmware I can't bring it to Samsung store to fix
please any suggestions?

Sounds more like a carrier problem. I'd ring them. Check your APN settings too.
Hi,
I have similar issues. Doesn't matter where I am and how good the network coverage is on all other phones around, my SGS2 keeps changing the coverage icon, from 1 to 4 "sticks" of indicator, or to no coverage state (crossed circle icon).
Sometimes the wireless is not working also, or juts gets very weak signal, though the signal is good on other devices near by.
When I try to turn data network (by pressing the power button and selecting data network activated from the pop up) sometimes it's not even showing the data network icon in the system bar (top of the screen), it's like being disabled data network or something.
I can answer a call and stay on conversation for no longer than a minute, then the signal goes dead and the phone just freezes, when I try to tap red button to end the call - no reaction, I have to turn the phone off.
When I try to make a call it just says "dialling" for ages with no result and eventually the phone freezes, so I have to turn it off and back on again.
Sometimes it turns off itself though the battery was showing almost full icon.
I went to O2 store, they gave me new SIM card, but it didn't help, so it's not a SIM issue.
I did a full (hard) reset - no help.
The guy from the O2 store told me, that I can root my phone, and I will not loose the warranty (I purchased the phone only one month ago), only thing I need to do is to revert it back to original state before bringing it (in case of hardware replacement).
But if it is not a software issue at all, so what's the point of rooting and having all the hustle, then reverting, etc... Can there be some hardware issues? I don't know: antenna, RAM, CPU, whatever???
I hope I've explained everything clearly enough. Any ideas would be appreciated. Thanks in advance.
What firmware are you on have you tried to Upgrade via KIES .
Rooting will void warranty and will also increase the custom rom counter from zero . Yes they can be reset in most cases .
Rooting will not fix anything at all .
Network is first check are you getting problems at all locations .
When in the O2 store did they check the signal ???
Choice return to service centre
Flash a stock Samsung firmware via XDA possible to also try a different modem via XDA .
None of these will fix hardware problem .
Personally i would factory reset the phone and check all the network details are correct on the phone then return to service .

when you have this problem check if you have an imei (*#06#) if the response is empty then you have to reflash...
Hi all again,
after posting my previous post I phoned my friend during a lunch break at work. We had a quite long conversation and the quality was perfect. Then on my way home I turned on data network and enabled GPS (LOL), then launched navigation app and it took me home without any bugs (I know my way home though I did it only for phone testing).
Now back home, sitting in my room and my SGS2 starts to fool around again: unable to turn on data network, poor wireless signal (but it's good on my PC), the network coverage icon turns into "no signal" state and comes back to normal again all by itself.
I will definitely test my phone again tomorrow on my way to work and in the office. But it seems like there's something wrong with the place that I live. I've moved in recently and must admit, that all my problems with the phone started only then. And I didn't noticed any bugs while at work or anywhere down town.
Meanwhile is there any way to scan/check the area around my flat? Maybe there's something wrong with the in house router, or maybe to many routers in surrounding flats, or some other equipment/hardware things messing up, or just a mysterious house blocking O2 network and hacking the phone LOL??
The only strange thing is that I'm having not just a network/coverage/wireless issues, but the phone freezes, battery full-empty-full-empty status randomly, etc...
BTW, my details:
Model: GT-I9100 (not a I9100G)
PDA: XWKJ1
PHONE: XXKI4
CSC: O2UKJ1
Android version: 2.3.5
Updated via KIES about a month ago, was working good until now. KIES says that at the moment I have the latest firmware.

Sim card works in other phones no problem
Is your SIM card recognized by the phone?
Does it have a SIM Serial Number? (Afaik you can e.g. use Z Device Test to see the SIM S/N)

Hey,
I was playing around with a few Custom ROMS today, and my mobile data stopped working. The APN settings are correct. I have flashed multiple ROMS but no luck. Even stock ICS ROM. I think I have the wrong modem/baseband combination.
My phone show H+ or 3G icon, but as soon as I try to use the internet, it vanishes. Wifi works fine.
Any ideas?
Seems like incorrect apn.. but you already say it's correct..
Try to Flash the stock modem..

Yes the APN is correct.
Could someone possibly tell me which firmware I should flash? I purchased my phone from Pakistan, but I'm not sure which region it is for. Will that make a difference?
Something happening with this phone. I had the same issue a few weeks later.
I tryed almost every modem available unsuccessful. Just my local carier can solve. I didn't known what they did, but solved until now.
Although your apn settings may be correct, they may need updating.
This sometimes happes in the uk.
Maybe if you tried deleting the apn settings out and then ringing your carrier network up, and asking them to sent your correct apn settings to your phone, maybe this could help.
Its not a dead cerainty but always got to be worth a shot mate

Had the same issue with my GS3 (I9300) after switching from those Straight Talk Bastards to AT&T:
Whereas Straight Talk simply f*cked up b/c of a collapse of their data network, so I assume (with nobody at ST saying a word for 2 days, of course.. ), it turned out that AT&T actually had deleted my new account - by mistake - after just one week of 'happy browsing'.
A trip to the local AT&T store solved the mystery and got me up & running again.
Unfortunately, though, it took the AT&T folks a while to figure it out, as they are not used to unbranded/international/ unlocked phones wanting to join their US network. (Don't even try to solve this over the phone, if you have a choice).
Kudos to the AT&T staff, though, as they got the problem resolved eventually. It definitely helped a great deal that my phone had been working just fine on their network just a week ago, so I was able to stand my ground and insist that the problem was at their end.
One of the reps - apparently without a clue - tried to tell me all sorts of BS, e.g. that the I9300 would not work on AT&T; that some Samsung phones supposedly don't work with their network... bla bla blub blub...
Fortunately, I knew better and told him so. Otherwise, he may have successfully gotten rid of me; making me search for the problem someplace else (a.k.a. giving me the run-around or making me chase my tail, etc. :banghead: )
Thanks to xda (and the Internet), however, I had all the knowledge necessary to make sure they get it back to work. Now I'm browsing the web again with 7Mbps Down/3Mbps Up speeds, using AT&T's really fast HSPA+ network here in the Chicago Northern Suburbs (close to O'Hare)... Yay!
Good Luck with finding the problem with your data loss issue!! :thumbup:
P.S.: Let me know if you need my APN settings; just for comparison (.. in case you are in the US, too).
Cheers,
AA

So the other week i put Lineage 14.1 7.1.1/7.1.0 rom on my samsung galaxy s3. I just switched to virgin mobile uk i was previously with giffgaff and giffgaff worked completely fine on this phone and rom. Yes my phone is unlocked. It was originally on a EE contract then i unlocked it and used it with giffgaff (02). The problem i'm having is when i put the Virgin Mobile UK sim into the phone and boot it up it says "Emergency Calls Only". When i go into the network settings and mobile networks and search for mobile networks it shows T-Mobile UK (EE which is who virgin mobile use), Vodafone, O2 and Three. (These 3 here have a padlock icon at the end while T-Mobile does not. Im guessing this is good. When i tap on it it refuses to connect and just tells me to try again later. It might be worth noting that when i start up the phone it briefly says "Emergency Calls Only - Virgin" at the top of the handset which i assume its connected for a second and then disconnects, loses connection or gets kicked off? I was on the phone to Virgin for 20 minutes and after i told the guy i was using a custom rom he did say it might be possible that Virgin does not allow anyone with a custom rom on the network.
Is this possible?
Has anyone else ever used a custom rom on Virgin Mobile UK, could you connect or did you have problems?
Thanks, Luke.
Have you set the apn settings?.
Beamed in by telepathy.
Apn settings affect data and should not affect voice service.
Only way to test the Virgin rep's assertion would need to flash back to stock and try the sim.

Quite sure my s3 on a custom kernel was once using vermin so i doubt they'll block custom roms from the network..
Without apn settings you might get as far as edge but certainly wont get 2g or higher.

I think flashing a stock ROM and then trying to connect is the only way to eliminate another possible factor.
Ok, i'll try stock rom then i guess. What do you mean "Without apn settings you might get as far as edge but certainly wont get 2g or higher." I don't get any signal at all so that can't be the problem.
Does or can anyone help me find a faster download link or mirror for a UK version of the stock rom. Samsung-Updates download link from rapidgator is so slow. 7 hours *tears*
The only other place is sammobile.com but that may only be a bit faster.

Tried stock rom, still no luck. Any other ideas? The Virgin guy said it could be a very very small chance that its the sim. But the fact it quickly displays virgin at boot up makes me think the sim is fine.
Maybe try the Virgin sim in another phone? Phone shows the correct imei? Not blacklisted?
Yeh I need to try this, literally no one in my family is on EE or anything using EE. What if the SIM does work in another phone what could be the problem with mine? Phone does show correct imei and it can't be blacklisted since it works with my giffgaff SIM.
Have you recently "moved house" from giffgaff to virgin and ported your number?. Your sim might not be activated. Im swinging with that from this point forward.
Text READY to 789678 from your old phone & SIM and your new sim if that doesn't work.
Moved house? Do you mean like switch from! Giffgaff to virgin? If so yes I just have switched. I was planning to keep my number but since I haven't got network I can't and haven't told them the PAC code.
How can I text a number of I don't have single or does that still work? ?
It is possible it's not active but the guy on the phone told me it was, he even got me to tell him the end 3 digits off the SIM to check.
The reason it's possible is because I ordered the SIM from them and the first one that was supposed to be delivered by YODEL was never delivered I called them that evening and they said we will just sent out another SIM anyway and so they did. This second SIM they sent out is the one I'm using and it might be the first SIM that is only active. But the fact the Virgin rep asked for the numbers of the sim and then told me it's active...I really don't know
Regardless, you must activate the sim, try the text i stated, if no joy try to call vm from the new sim and tell them the pac code then they swap the numbers over. If it doesn't ring out then I'd take it to carphone warehouse and ask them to set up the new sim card.
The sim is active as in it is alive and sending a response but it looks like the actual line attached to it isn't active. Sim cards must be activated to prevent the number attached to it from going stale as there is a forever decreasing amount of 07 numbers available for networks.
I'm convinced that the sim isn't activated, it will currently be a payg sim and might need to be topped up to activate it, then you transfer any number and remaining credit to your new contract/payg sim (if required).
You should still be able to call the carrier on an inactive line so long as the sim is alive. Failing that use a landline.

Well i've called virgin again and they say it is active. It has been over 24 hours. I've tried it in 2 other phones and it just doesn't connect. They even sent out a 3rd sim now and same problem. Definitely a problem there end then, i'm thinking?

Did you try the text to activate the sim?. As I said, the sim can be active as in valid to the system but not necessarily activated to prevent the number going stale and being returned to the pool after 6 months on no use.. Even if there is no signal at all you should have at least tried it once.
Maybe the sim is payg and needs a topup to activate. That could be another restriction.
I don't have any simcard documentation so I'm shooting at fish in a barrel but surely 3 sim cards on the trot can't be faulty. Something is amiss..
